Fosi Audio 48V GaN Power Supply Unit for TB10D,BT20A PRO,V3,ZA3

The power supply I ordered arrived in good condition and working order once I received it. Supply works exactly as advertised. This order got hung up in US Customs handoff to the Post Office and it appeared to be lost. However Fosi Customer Service got engaged and somehow spurred finding the package and getting it moving from Customs to the Post Office for delivery. Their help was greatly appreciated.

Got the Fosi Audio ZA3 with the 48V GAN Power Supply and the ZD3 to go with a Wiim Pro Plus, through GR Research crossover modded Neumi BS5s... and it all sounds exquisite! Quality components at real people prices!

Worked very well for my Aiyima A08 Pro driving 2 8" Cambridge Soundworks drivers in undersized enclosures I bought on Amazon and lined the walls with damping material and stuffed with cotton in an attempt to compensate for the enclosure being undersized. This power supply definitely gave them quite a bit more punch than the stock power supply. I first tried a Skuaike 48 volt power supply but was very disappointed with the noise they produced going through my speakers. I am also using these for two Aiyima AO7 Max's. There is still some noise through the speakers but not nearly as noticable as with the Skuaike power supply. I'm sure the noise is not helped by the wiring in the house I live which is over 100 years old.

Its is a good power supply that conforms to all standards.

It costs more than the TB10D and took a long time to get, but it's a game changer. Definitely worth it if you have high draw speakers.
